FOUNTAIN-SPITTOON.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application iled. January 29, 1906. Serial No. 298.309.

To all whom it may concern:

Be it known that I, THEoDoRE G. LEwIs, a

citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Fountain-Spittoons, of which the following is aspecification.

This invention relates to the flushing or fountain cuspidors used principally by dentists.

One of its objects is to so construct a support for the spittoon-bowl that all valveseats and inlet and outlet connections are contained in a single casting or housing, which also forms a common receptacle for all waste fluids.

Another object is to so construct and ary range said support and valve-housing that it serves as a common receptacle into which all such Waste fluids are discharged directly instead of being iirst discharged into the bowl and thence into the drain or waste pipe.

A further object is to so construct the valves that they can be readily opened for draining the various pipes to prevent freezing of the same during the night.

The. invention has the further object to render the valve mechanism neat and compact and easy of access, so that the several valves can be conveniently manipulated from the same side of the spittoon.

. in line 4 4, Fig. 2.

In the accompanying drawings, consisting of two sheets, Figure 1 is a vertical central section of the improved spittoon. Fig. 2 is a horizontal section in line 2 2, Fig. l. Fig. 3

, construction of the iiushing device and its controlling-valve. Fig. 9 is a horizontal section in line 9 9, Fig. S. Fig. 10 is a cross-section in line 10 10, Fig. 9.

Similar letters of reference indicate corresponding parts throughout the several views. Referring to the construction shown in Figs. l to 7, A' ish the bowl, which may be of ordinary construction, and B indicates a valve box or housing arranged horizontally below the bowl and serving as a support for the same. This box is closed on all sides and provided at its top with a neck b, arranged in line with the central discharge-o ening of the bowl and secured to the latter y a suitable union b', preferably arranged within said opening and neck. In its bottom the box is provided with a depending nipple c, to which a drain or waste pipe C is attached.

D indicates a water-inlet chamber ar ranged in the rear vportion of the valve-box B and having a depending nipple d, to which a water-supply pipe D is connected.

E is a Hush-head or rose arranged centrally in the bowl A and supported by an upright pipe e, passing through .the union b and connected at its lower end to a valve-case e', arranged within the box B. This valve-case is connected with the inlet-chamber D by a horizontal pipe e2, also arranged in the valve# box. The case e contains a valve e3, preferably consisting of a tapering plug which is capable of sliding as well as rotating in the case. This plug has a longitudinal passage Which is in constant communication with the pipe e2 and a lateral port e4, adapted to register or break register with the flush-pipe c by turning the plug. The stem of the plug passes through a stufling-box or capped bushing in the front wall of the valve-box B and terminates in an external head or .knob for manipulating it, as shown. The plug is yieldingly held in its seat by a springf, applied to its stem between a shoulder thereof and 'the cap of said bushing. Upon Withdrawing the plug from its seat by a pull on its stem any water in the Hush-pipe e is allowed to drain through the open front end of the valve-case e into the valve-box B and thence into the sewer.

The rotary movement of the valve-plug e3 lmay be limited by a pinf3, projecting from its stem into a segmental groove f4, formed in the bushing f, this groove being of sufficient depth to permit the necessarysliding movement of the plug.

G is the tumbler-tray, and g its drain-pipe, which leads from its bottom and enters `the top of the valve-box Bthrough a stuffingbox g. H is. the water-supply pipeof the IOO stem of this valve extends through a capped bushing 71.2 in the front wall of the valve-box B, and the valve is held in its seat by a spring h3, applied to its stem between a collar of the latter and the cap of said bushing. This construction permits the valve to be withdrawn from its seat like the valve e3 for draining the contents of the tumbler supply-pipe H into the valve-box B.

I is the saliva-ejector, and t its jet-nozzle, with which the usual hose or tube t is cony nected. This nozzle preferably extends a short distance into the main passage of the ejector, and its inner end is slightly beveled, as shown in Fig. 4. The lower end of this ejector communicates through a valve-chamber 7 with the inlet-chamber D. In this valve-chamber is a valve lc, which is preferably identical in construction with the valve g2, the same being held in its seat by a spring k2. The upper end of the ejector is connected with the interior of the valve-box B by a tube l, the lower vertical portion of which enters a slidable sleeve m, which passes through a stuH'mg-box m in the top of the valve-box B. The sleeve is closed at its lower end and provided in its side near said end with a discharge opening 'm2, which communicates with the valve-box B in the depressed position of the sleeve (shown in Figs. 4 and 6) and through which the water after having passed through the ejector flows into the valve-box. Vithin its closed lower end the sleeve is provided with an upwardly-extending conical valve or plug m3, which closes the lower end of the tube Z when the sleeve is elevated. When the sleeve is thus cut off from the valve-box and the ejector-valve 7c is opened, as shown in Fig. 4, the current is reversed, the water passing from the inlet-chamber through the jet-nozzle and the ejector-tube and flushing the same.

N is a goldvtrap or cavity arranged in the bottom of the valve-box B underneath the discharge-opening of the bowl A and provided at its lower end with a discharge-opening which is normally closed by a screw cap or plug n.

The valve-box is provided in its bottom with a screw-threaded socket o, adapted to receive the upper end of a rod or standard 0, which supports the cuspidor.

By the improved construction herein shown and described the spittoon-bowl connection or neck I), the valve-seats, and all inlet and outlet nipples are contained .in a single casting or housing. All waste fluids from the lflush device E, the tumbler-drain g, and the ejector-drain Z are discharged directly into the common receptacle or wastechamber formed by the valve-box and not first into the bowl and then into the drainpipe, as is usually the case. The controllingvalves of the Hush device E, the tumbler supply-pipe H, and the ejector I are all inclosed by the valve-box, and any leakage from these valves drains intol the boX, preventing soiling of the floor or damage to the premises.

The stems of the several valves are arranged in a small compass at one end of the valve-box, enabling the dentist to conveniently manipulate any of them .from a single point without leaving his place beside the dental chair.

To prevent freezing of the water-passages of the spittoon during the night, the dentist or other operator before leaving his office simply pulls the stems of the several valves e, g2, and le', when the water in the flush-pipe e, the tumbler supply-,pipe H, and the ejector I will drain into the valve-box B, as hereinbefore described.

As there is no water-pressure in the valvebox, ordinary joints, such as shown in the drawings, may be employed for the various valve-stems and the pipes g and l, thus simplifying the construction of the spittoon and reducing its cost of manufacture.

In the modified construction shown in Figs. 8 and 9 a perforated circular flush-pipe E, arranged in the spittoon near its upper edge, is substituted. for the rose E. This pipe is connected with the inlet-chamber D by an eX- ternal pipe P, a nipple p, and avalve-ehamber p, arranged centrally in the rear portion of the valve-box. This valve-chamber, which takes the place of the corresponding'chamber c of the. first-described construction, contains a valve or plug g, preferably constructed like the valves g2 and 7c and operating in the same manner. The other parts of this modification maybe identical with the corresponding parts of the construction shown in Figs. 1 to 7.
